Question

A conductor has a 14.4 × 10^-19 coulomb positive charge. The conductor has ______ 

(Charge on electron = 1.6 × 10^-19 coulomb)

Options

• 9 electrons in excess.

• 27 electrons in short.

• 27 electrons in excess.

• 9 electrons in short.

Answer 1

A conductor has a 14.4 × 10^-19 coulomb positive charge. The conductor has 9 electrons in short.

Explanation:

A positive charge indicates an electron deficiency.

Number of electrons = `(14.4 xx 10^-19)/(1.6 xx 10^-19) = 9`
